(2) Centralized store control system 31

In addition, FIG. 3 shows a configuration diagram of the store centralized control system 31 of the present invention that collectively controls these devices installed in the store 1. The store centralized control system 31 of the embodiment includes a controller 32 as a control device. The controller 32 is composed of a microcomputer having a processor. The controller 32 includes, as its functions, a fryer ventilator control unit 33 and air-conditioning control.

(3) Operation of the fryer 18

Next, the operation (cooking of fried food) of the fryer 18 will be described with reference to FIG. 4. FIG. 4 shows the transition of the operating state of the fryer 18. When the worker presses the power switch 54 from the power-off state (i), the fryer 18 is in a power-on state. However, at this stage, the heater is off (ii), and the heater 53 has not been energized. From the heater-off state (ii), when the worker presses the ready-to-heat button 56, the fryer 18 starts to energize the heater 53 (heater-on state) and changes to the heating state (iii).

In the heating state (iii), the oil temperature rises from normal temperature to time t1, and the oil temperature rises from temperature T1 to time T2 to time T2, and becomes a cookable state (iv), maintaining the temperature T2. The temperature T1 is a predetermined waiting temperature higher than the normal temperature, and the temperature T2 is a cooking temperature higher than the waiting temperature T1. In addition, time t2 is a value smaller than time t1. When the predetermined time t6 elapses in the non-operation state in this state, the fryer 18 is in the energy-saving mode state (v), and the oil temperature is maintained at the temperature T1. When the ready-to-heat button 56 is pressed in this state, the fryer 18 becomes the heating state (iii) again.

On the other hand, if the cooking switch 21 is turned off (the cooking basket 21 is raised) and the menu number switch 57 is pressed, the cooking basket 21 is lowered into the oil tank 19 by the lifter 20, and the lifting switch 43 is Is on. Then, when a predetermined cooking time (timer) elapses and the cooking of the fried food is completed, the cooking basket 21 is automatically raised by the lifter 20, and the lift switch 43 is turned off.

(4) Control of the ventilation device 22 of the controller 32 (part 1)

An example of control of the ventilation device 22 of the controller 32 will be described below with reference to FIGS. 5 to 7. FIG. 5 is a diagram illustrating the operation of the air supply fan 23 and the exhaust fan 24 of the ventilation device 22, and FIG. 6 is a flowchart illustrating the control of the ventilation device 22 (the air supply fan 23 and the exhaust fan 24) of the controller 32 Illustration. In addition, FIG. 7 shows the control of FIG. 6 in a timing chart.

As described above, the power consumption of the fryer 18 and the on / off state of the lift switch 43 are input to the state data receiving unit 39 of the fryer ventilator control unit 33 of the controller 32. At the ventilation device instruction determination unit 41 of the fryer ventilator control unit 33, at a period of a predetermined time t4, in step S1 in FIG. 6, it is determined that the instantaneous power of the fryer 18 is the maximum during a predetermined time t5 in the past. Whether the value is greater than or equal to a predetermined ventilation HIGH threshold value, or whether the number of times the lift switch 43 is turned on is greater than or equal to one during a predetermined time t5 in the past.

At present, the fryer 18 is in the heating state (iii) or the cookable state (iv) in FIG. 4. During the period when the power consumption is increased and the predetermined time t5 has elapsed, the maximum instantaneous power of the fryer 18 may be When the ventilation high threshold value (larger power W3) is greater than or equal to once, or if the lift switch 43 is turned on once during the predetermined time t5 in the past, the ventilation device instruction determination unit 41 proceeds to step S2. And set the ventilation HIGH mode (Figure 5). The setting of the ventilation high mode is transmitted from the ventilation device instruction transmitting unit 42 to each inverter 51 and 52, and each inverter 51 and 52 sets the operating frequency of the air supply fan 23 and the exhaust fan 24 to X2 (Hz ).

Since the operating frequency X2 is a faster frequency, the amount of air supplied by the air supply fan 23 is increased, and the amount of air discharged by the exhaust fan 24 is also increased. Therefore, the air exchange amount of the ventilation device 22 is increased. When the fryer 18 is in the heating state (iii) or the cookable state (iv), a large amount of odor is generated, and the surrounding temperature also rises, the ventilation amount of the ventilation device 22 is increased, and the self-frying is thereby performed. The smell generated by the machine 18 is strongly discharged to the outside, and the temperature rise of the cooking chamber 14 is also effectively suppressed.

On the other hand, when the fryer 18 is changed from the cookable state (iv) in FIG. 4 to the energy-saving mode state (v), the power consumption is also reduced, and the lift switch 43 is also turned off. Regarding the ventilation device instruction determination unit 41, the instantaneous maximum power value of the fryer 18 was not greater than or equal to the ventilation high threshold once during a predetermined time t5 in the past, and the lift switch 43 was also performed once during a predetermined time t5 in the past. If it is not turned on, proceed from step S1 to step S3.

In this step S3, the ventilation device instruction determination unit 41 determines whether the instantaneous maximum power value of the fryer 18 is equal to or greater than a predetermined ventilation MID threshold value (power W1) during a predetermined time t5 in the past. The ventilation MID threshold (power W1) is in a relationship between the ventilation MID threshold (power W1) <ventilation high threshold (power W3). If the fryer 18 is in the energy-saving mode state (v) in FIG. 4, although the power consumption is reduced, the maximum value of the instantaneous power is greater than or equal to the ventilation MID threshold (power W1), so the ventilation device instruction determination unit 41 proceeds from step S3 Proceeding to step S4, the ventilation MID mode is set (FIG. 5).

The setting of the ventilation MID mode is transmitted from the ventilation device instruction transmitting section 42 to the inverters 51 and 52. Each inverter 51 and 52 uses the operating frequency of the air supply fan 23 and the exhaust fan 24 as X1 (Hz). . Since the operating frequency X1 is lower than the operating frequency X2 (X1 <X2), compared with the case of the ventilation high mode, the amount of air supplied by the air supply fan 23 is reduced, and the amount of air discharged by the exhaust fan 24 is also reduced. The ventilation amount of the ventilation device 22 is reduced.

When the fryer 18 is in the energy-saving mode state (v), the amount of odor generated is small, and the ambient temperature rise is small. Therefore, even if the ventilation amount of the ventilator 22 is reduced, the odor generated by the fryer 18 is reduced. It is also discharged to the outside unhindered, and the temperature rise of the cooking chamber 14 is also suppressed unhindered.

Then, if the fryer 18 is in the heater-off state (ii) or the power-off state (i), the maximum value of the instantaneous power of the fryer 18 will not be greater than or equal to the ventilation MID threshold ( Electric power W1), so the ventilation device instruction determination unit 41 proceeds from step S3 to step S5, and sets the ventilation LOW mode (FIG. 5).

In the setting of the ventilation LOW mode, the inverters 51 and 52 are transmitted from the ventilation device instruction transmission unit 42, and the inverters 51 and 52 stop the operation frequency of the air supply fan 23 and the exhaust fan 24 at, for example, 0. Therefore, the air supply and exhaust of the ventilation device 22 are not performed. However, since the fryer 18 does not generate an odor, and the temperature of the cooking chamber 14 does not increase, the odor does not spread to the store. The cooking chamber 14 The temperature will not be abnormally high.

In contrast, when the fryer 18 is in a power-off state (i) or a heater-off state (ii), the supply and exhaust of the ventilation device 22 is not performed, and the air in the air-conditioned shop does not need to be exhausted to There is no need to introduce outside air into the store, thereby preventing an increase in the load of the air-conditioning apparatus 17 that performs air conditioning in the store of the store 1.

FIG. 7 shows the above-mentioned control through a timing chart. The uppermost layer is the mode of the ventilation device 22, the middle layer is the on / off state of the lift switch 43, and the lowermost layer is the operating state and power consumption of the fryer 18. In this embodiment, the fryer 18 changes from the heating state (iii) to the cookable state (iv), the power consumption increases, and the maximum instantaneous power value is repeatedly greater than or equal to the ventilation high threshold multiple times. The ventilation device 22 For ventilation HIGH mode. Then, when the cooking is started, the lift switch 43 is also turned on.

Then, if the fryer 18 is in the energy-saving mode state (v), since the power to the heater 53 is also temporarily turned off, the power consumption becomes zero. However, the ventilation device instruction determination unit 41 determines whether the instantaneous electric power maximum value of the fryer 18 is not greater than or equal to the ventilation high threshold once or not at step S1 in FIG. As long as the lift switch 43 has been turned ON once during the elapse of the predetermined time t5, it is possible to perform the process from step S1 at the time of the predetermined time t5 from the time when the latest instantaneous maximum electric power value is equal to or greater than the ventilation high threshold (the lift switch 43 is turned on). The process proceeds to step S2 and the ventilation high mode of the ventilation device 22 is continuously set.

Then, the predetermined time t5 is the confirmation time of the mode change, and the ventilator instruction determination section 41 even when the fryer 18 is switched from the cookable state (iv) to the energy-saving mode state (v), that is, even when the When the operating state of the fryer 18 controlled by reducing the ventilation amount of the ventilation device 22 is changed, the current ventilation amount is maintained during the predetermined time t5 (ventilation HIGH mode).

In addition, in FIG. 7, in the energy-saving mode state (v), the instantaneous maximum electric power value of the fryer 18 is greater than or equal to the ventilation MID threshold, so the ventilation device instruction determination unit 41 proceeds from step S3 to step S4 and sets The ventilation MID mode, but after that, even in the power-off state (i), similarly, during a predetermined time t5 from the moment when the maximum value of the latest instantaneous power is equal to or greater than the ventilation MID threshold, the process proceeds from step S3. Go to step S4, and continue to set the ventilation MID mode of the ventilation device 22.

Then, even in this case, the confirmation time of the mode is changed at the predetermined time t5, and the ventilator instruction determination unit 41 changes the state of the fryer 18 from the energy-saving mode state (v) to the power-off state (i) even if That is, even in the case of a change in the operating state of the fryer 18 that is controlled to reduce the ventilation amount of the ventilation device 22, the current ventilation amount (exchange) is maintained during a predetermined time t5. Gas MID mode).

As described in detail above, in the present invention, since the controller 32 of the store centralized control system 31 of the store 1 controls the ventilation device 22 according to the operating state of the fryer (cooker) 18 provided in the store 1, it can respond to During cooking, an operating state of the fryer 18 that generates an odor and raises the temperature is controlled by the ventilation device 22 to appropriately control the amount of ventilation.

Therefore, as in the embodiment, the ventilation device 22 constituted by the exhaust fan 24 and the air supply fan 23 prevents the diffusion of odors into the store and prevents the increase of the air-conditioning load in the store due to the ventilation, so as to reduce consumption. Reduction of electricity.

In this case, in the embodiment, since the controller 32 controls the ventilation according to the power consumption of the fryer 18, as the power consumption (the maximum value of the instantaneous power) of the fryer 18 increases, the ventilation rate is increased. The air device 22 can control the amount of air exchange of the air exchange device 22 to be optimized during the operation of the fryer 18.

In addition, in the embodiment, the controller 32 determines whether cooking is being performed based on the operation of the up / down switch 43 of the cooking basket 21 included in the fryer 18 (in a heating state, a cooking state, etc.). ), The ventilation device 22 is controlled in such a manner as to increase the ventilation volume, so the ventilation volume of the ventilation device 22 can be controlled to be optimized during cooking of the fryer 18.

In addition, in the embodiment, since the controller 32 adjusts the ventilation amount of the ventilation device 22 in stages according to the three phases of ventilation HIGH mode, ventilation MID mode, and stop, the ventilation device can be adjusted with good accuracy. The ventilation amount of 22 can effectively reduce the power consumption of the store 1.

In addition, in the embodiment, the controller 32 is maintained for a predetermined time t5 even when the operating state of the fryer 18 controlled to reduce the ventilation amount of the ventilation device 22 is changed. The current amount of ventilation allows the odor generated after cooking of the fryer 18 to be discharged to the outside without hindrance.

(Example 2)

(5) Control of the ventilation device 22 of the controller 32 (No. 2)

Next, another embodiment of the control of the ventilation device 22 of the controller 32 will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart illustrating the control of the ventilation device 22 of the controller 32 in this case, and FIG. 9 is a timing chart showing the control of FIG. 8. In addition, the steps shown by the same symbols as in FIG. 6 indicate the same operation, and FIG. 9 is the same as FIG. 7. The top layer is the mode of the ventilation device 22 in this case, and the middle layer is the on / off state of the lift switch 43. The lowermost layer is the operating state and power consumption of the fryer 18.

In the case of this embodiment, in step S1A corresponding to step S1 in the flowchart of FIG. 6, it is determined whether only the up / down switch 43 of the fryer 18 is turned on. Next, when the lift switch 43 is turned on, the process proceeds from step S1A to step S2. In the same manner as described above, the ventilation high mode of the ventilation device 22 is set. When the lift switch 43 is turned off, the process proceeds to step S3. The situation in step 6 is the same, and steps S3 to S5 are performed.

When the lifting switch 43 is turned on for cooking, as in this embodiment, when the lifting switch 43 is turned on, the ventilation device 22 can be set to the ventilation high mode, and the ventilation amount of the ventilation device 22 is increased, which will forcefully change The odor generated by the fryer 18 is discharged to the outside, and the temperature rise in the cooking chamber 14 can be effectively suppressed.

However, in the case of this embodiment, as shown in FIG. 9, only when the lift switch 43 is turned on, the ventilation device 22 is in the ventilation high mode, and during other periods, it is in the ventilation MID mode (the process proceeds from step S3). When it proceeds to step S4), there is a concern that the odor generated after cooking is diffused. In this case, it may be delayed in such a manner as to shift to the MID mode after a predetermined time has elapsed after the lift switch 43 is turned off.

In addition, in step S1 of FIG. 6 of the first embodiment, the ventilation device instruction determination unit 41 determines whether the maximum instantaneous power of the fryer 18 is equal to or greater than the ventilation high threshold during the predetermined time t5 in the past, or whether During the past predetermined time t5, the number of times that the lift switch 43 has been turned on is greater than or equal to one, but it is not limited to this. The present invention also determines that the maximum instantaneous electric power of the fryer 18 is greater than or equal to only during the period of the predetermined time t5 in the past. The case of the ventilation high threshold is also effective, and the present invention is suitable for a case where the information of the lift switch 43 of the fryer 18 cannot be obtained.

In addition, in each of the embodiments described above, the power consumption (maximum instantaneous power) of the fryer 18 is used to determine the operating state of the fryer 18, but it is not limited to this, and the temperature of the fryer 18 may also be used (The temperature of the fryer 18 itself, the temperature of the oil, the temperature of the air above the fryer 18, etc.), and the operating state of the fryer 18 is determined. In this case, the ventilation device 22 is controlled such that the amount of ventilation increases as the temperature rises (from the ventilation LOW mode to the ventilation MID mode, and from the ventilation MID mode to the ventilation HIGH mode).

Specifically, it can be set as follows. For example, in step S1 of FIG. 6, the ventilation device instruction determination unit 41 may determine whether the temperature of the fryer 18 is equal to or greater than the ventilation high threshold (in this case, the value of the temperature) during a predetermined time t5 in the past. In step S3, it is determined whether or not the temperature of the fryer 18 is equal to or greater than the ventilation MID threshold during the past predetermined time t5 (also in this case, a value lower than the ventilation high threshold).

In addition, in the embodiment, the ventilation amount of the ventilation device 22 is adjusted according to the three phases of the ventilation LOW mode, the ventilation MID mode, and the ventilation HIGH mode, but it is not limited to this, and there may be more phases The adjustment can also be performed in a continuous conversion manner.
